Independent web studio, founded 2023. Based in Sirajganj, Bangladesh - working with clients across the UK, the Netherlands, the US and beyond.
You work directly with the people building your site. No middle managers. No account executives. Just real conversations and real progress, every week.
Explainerium started in 2023 as a one-person studio. Before that, Najir was building websites and brands for clients on Fiverr, where the work earned hundreds of five-star reviews and a queue of repeat customers.
The studio exists for the same reason most studios exist: to do better work, with fewer constraints, for clients who want a long-term partner instead of a faceless agency.
Today the studio works with founders, agencies, and in-house teams across twelve countries - usually as a quiet partner doing the heavy lifting behind the scenes.
No rushed work. No corner-cutting. Every project is hand-built to a standard we are proud to ship.
We do not hand over and disappear. We stay in your corner long after launch - for tweaks, growth, and the occasional fire drill.
Clean code, sane architecture, predictable performance. The kind of build the next developer thanks you for.
Fixed quotes, clear scope, transparent timelines. If something changes, we tell you before the invoice does.
